Ionic Bonding Flashcards
What happens with electrons in an Ionic Bond?
Electrons are transferred between two atoms:
- Shared electrons are transferred to atom with highest electronegativity
- VERY unequal sharing
What types of atoms does Ionic bonding occur between?
Metals and Nonmetals (cations and anions)
What causes Cations and Anions to form Ionic bonds?
Their opposite charges (opposites attract)
What force holds Ionic Compounds together?
Electrostatic Forces (Electrostatic Attraction)
What term is used for ionic compounds (instead of “molecule”)?
Formula Unit
What is the form of Ionic Compounds at room temperature?
Crystalline Solid (Crystal Lattice)
(a crystal lattice occurs when Ions are packed together)
What is the Melting Point and Malleability of Ionic Compounds?
- High Melting Points
- Low Malleability
(This is due to the strength of Ionic Bonds/Compounds)
Can Ionic Bonds conduct electricity?
Yes - when dissociated in water or melted
What happens when Ionic Compounds dissolve in water? What is this process called?
- Electrostatic forces reduce (bonds break up)
- This process is known as dissociation (or solvation)
(when Ionic bonds break up, electrons become more delocalized)
If you see this card, practice drawing a complete Lewis dot structure for a random ionic compound
Do it :)
